[Dokan API]: The admin is facing restrictions while creating and updating or trying to assign a product to a vendor.

[J-H-Mojumder]

Describe the bug
Few problems regarding the Dokan Product Create and Update API.

1. The admin can not create a product by changing the post_author value of it at the time of creation.
2. The admin is not being able to change the post_author value of a product created by him/her to assign the product to a different vendor.
3. The admin is unable to edit the product of any vendor.

To Reproduce

1. Create a product via API with a post_author value of a vendor other than the admin himself/herself.
2. The post_author ID will remain the same as the admin's ID.
3. The Same thing happens if the admin tries to modify the post_author value of his/her own product.

Expected behavior

1. The admin is supposed to be able to create a product with the post_author value so that the admin can assign the product to a vendor at the time of creating it.
2. The admin is supposed to be able to edit the post_author value of any other vendor.
3. The admin is supposed to be able to edit the product of any other vendor in the marketplace.

Environment:

• Dokan Version: [v3.7.1]
• Dokan Pro Version: [v3.7.7]
• WooCommerce Version: [v7.0.0]

@J-H-Mojumder This is how the REST API for products has been created five years back. Have you consulted with @Mohaiminulislam1989 bhai for this enhancement?
